I NHED STATES ORVILLE OOOLEY, OF BATAVIA, NE\V YORK, ASSIGNOR TO THEJOHNSTON HARVESTER COMPANY, OF SAME PLACE.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 321,692, dated July 7,1885.

Application filed April 16, 1884.

ing device placed wholly upon the upper side.

I of the breastplate and operated upon directly by the needle-arm;second, to arrange for the successful operation of the tucker, giving ita positive movement, even if its actuatingspring should becomeinoperative; and, third,

'20 to afford means for preventing the entanglement of the twine carriedby the needle, and still assure the operation of the tucker at eachforward movement of the needle and have the parts at all times work inunison and in such manner that the springing or yielding of the needlewill not act deleteriously in the tying of the knot.

I attain these objects by the mechanism illust-rated in the accompanyingdrawings, in 0 which Figure 1 is a plan view of the breastplate with theneedle in position ready to act upon the tucking-operating mechanism inits forward thrust. Fig. 2 isa side elevation of the needle as it hasreached the extent of its 3 5 throw and just at the point of receding;and Fig. 3 is a perspective view taken from the side upon which thetucker is pivoted, with the needle at the point when the tucker firstcomes in contact with the twine.

Similar letters refer to similar parts in the several views.

A is the breast-plate having the slot at, and upon which is mounted thetucker B and the tucker-operating lever 13. Upon the free end 5 of thislever B is pivoted the friction-roller I).

G is a stud,which pivotally secures the tucker to the breast-plate, andaround which is coiled the spiral spring 0. This stud is made fast tothe breast-plate, with the end of the (No model.)

coil secured to the head of the stud, so that the spring-coil iscompressed when in practical operation.

0 is alug placed upon the tucker about midway between the pivotalconnection and the point. To this stud c is secured the reverse end orthe spring in such manner that it is compressed in the downward throw ofthe tucker and causes the tucker to return to the position shown in Fig.1 upon the backward movement of the needle.

The point of the tucker is made slightly hooking upon its lower edge, soas to catch and hold the binding-twine and not allow it to slide overthe end while being carried to theknotting device. The rear end of thetucker extends outward and past the edge of the breastplate, for apurpose hereinafter described.

D represents an arm of the bundle-discharger, the operating mechanism ofwhich is not shown; and as I claim nothing upon the ma chinery foroperating the needle, knotting de vice, 810., it will not be necessaryfor me to describe the working of the said parts further than isrequired for the conjunctive action 7 with my tucking device.

It will be observed that the tucker-lever is slotted, as at 6, throughwhich passes the headed bolt 6', and by which the lever is held in closeproximity with the breast-plate, and yet allow of the necessary swingfrom the pivotal connection e In order that the roller upon the levermay be brought into peripheral con tact with the needle-arm, as well asto overlap the tucker-point, it is made of greater diameter than thelateral face of the lever at the place where the roller is pivoted.

It will be observed that the entire tucking mechanism is located uponthe upper side of the breast-plate, thus obviating the necessity 0 of ashield to serve as a preventive against the accumulation of straws orother deleterious matter at this point to interfere with the practicalworking of the machine.

In the practical operation of my tucking de- 5 vice the grain to bebound is, by suitable mechanism, placed upon the table locatedunderneath the breast-plate, and when a sufficient quantity is gatheredto form a bundle the needle is automatically brought forward upon theare of a circle, of which the end of the arm is the center, so as tocarry the twine around the gavel. In the forward movement the needle-armcomes in contact with the roller which lies in the path of the needle,and causes the lever to swing upon the pivotal point, and in so doing itimpinges against the rounded end of the tucker, causing it to swingacross the slot a, so as to come in contact with the needlein itsforward movement and bring the binding-twine in contact with theknotting device, whereby the knot is tied, and (by suitable mechanism)the bundle is discharged.

The purpose of the heel-extension to the tucker will now be explained.It will be seen that when the tucker is in the position shown in Fig. 3the rear part extends past the bed plate, and were it to remain in thisposition until the revolution of the bumlle-diseharger the arm wouldstrike this extended heel, and by so doing bring the tucker back to itsnormal position ready for another operation, so that should the springbecome inoperative the bundle will still be discharged in a boundcondition without the aid of the spring; yet I prefer using the spring,for in so doing the tucker plays freely with but little friction, andthe operation is rendered doubly secure.

I am aware that prior to my invention tuckers have been made having apositive movement. Therefore I do not claim such a movement, broadly;but

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is

The combination of the needle, the tucker, the tucker-securing bolt uponwhich it turns, and the bundlediseharging arm made to act directly uponthe rear extension of thetucker, substantially as herein described.

ORVILLE COOLEY.
